The Calendar and Contacts Server (CCS) implements the CalDAV and CardDAV protocols. These protocols are standards-compliant. The service allows users to store and edit calendar and contact information. When you install the related plugin form WHM > cPanel > Manage Plugins > Install Calendar and Contact Server interface, quite a few packages are installed as dependencies for the service, there are in general 18 of such packages:

However, the main package that contains all the essential files and directories for the service is this one:
rpm -qa | grep -i cpanel-ccs-calendarserver
cpanel-ccs-calendarserver-9.2.a-71.73.1.cp1180.gfbd0e1167.x86_64
With so many packages and files installed, it's sometimes hard to find a specific file that you might need for troubleshooting purposes. The most important of such files are of course the log files. The main location of the log files for the CCS service is this: (You can also see the content of the directory):
